TYPE'SETTING MACHENE.

Specification of Letters Patent.

Patented Nov. 27, 1h06.

To all whom t muy conclu-11,:

Be 1t known that I, FRANK MCCLINTOCK, of Mount Vernon, county of ltchester, and

IState of New York, have invented a new and useful ImprovementinType-Setting Machines, of which the following is a specification.

My invention is an improvement in typeejecting mechanism heretoforeinvented by Ine and shown in United States Patent No. 702,458, issuedJune 17, 1902.

The objects of this invention are to provide means whereby theratchet-teeth on the type-ej ector bars will be more promptly direngagedfrom the teeth of the actuating roll or shaft and prevented from beingaccidentally thrown again into gear with the ratchetteeth of therotating shaft and also to siniplify and reduce the cost of themanufacturing and assembling of the parts` The invention is shown in theaccompanyfl ing drawings.

Figure 1 is a sectional perspective view showing the parts in theirnormal position when not in operation. Fifa 2 is a similar view showingoncof the lreyllevers depressed and the corresponding type-ejector barin action.

Similar reference characters refer to similar parts in each of theviews.

Iii the drawings, 1 is the bed-plate of the machine.

2 is the ty e-case, which has plurality of type-charme s 3, each channelcontaining type 4 of one kind only. Each type-channel is provided withan opening 5 in 'its front of suitable width to allow of only a singletype being ejected therefrom and anoiher opening 6 in the rear throughwhich the forward end 7 of the type-ejector may enter.

l() represents the type-ejector bars, which have ratchet-teeth 13 neartheir rear ends and are provided with a latcrn.lly-'projecting lip l2.The type-ejectors 7 are screwed into theI front end of the ejector-barsl() at the point 9. y

15 is a pivoted plate to which the campi ics H are secured. Bydepressing tlfif; plate al'. of the acting ejector-bars may be thrownont ot action, and thus the delivery of type rrcsted.

The type-ejector bars are retained in their proper position parallel loeach other and guided longitudinally by means of two bearings S and 15is the ratchet-toothed roll, which is caused to rotate continuiiusly byany convenient power.

.6 represents the rods whereby the rear ends of type-cjector bars areelevated to bring the ratohehteeth 13 into gear with the ratchet-teethon the roller 15u. lhe rods 1G are actuated by means ol' a key-lever 24,having a suitable finger-button Upon the depression of the `lingerdrey25 the rod 16 is elevated, as shown in Fig.y 2, which raises the rearend of the ejector-bar 10, thereby causing the ratchczt-teeth 13 tobecome engaged by the ratchotetceth on the rapidly'- rotating roller15a, which thereupon forces the ejector-bar forward, and the flat end 7enters the type-channel and engages with the lowest type in the channel3 and eject-s it therefrom through the opening 5 in the usual manner, Assoon as the ejector-bar Vl() begins to move forward the lip 12 engageswith the cani-piece 14, thereby preventing the said riliector-bar fromdropping down andthus becoming disengaged from. the ratchet roller 15ZLuntil it is moved forward the rcu quired distance'to force the typeentirely out of the type-channel.

It is very desirable that the weight of the ejector-bars bc kept aslight as possible, and it has been found in V)raclfice that the 'weightof the cjectonhars alone is generally insullicient to insure 'therequired quick dropping of the rear end of the ejector-bar 1i),particularly when a considerable number' ol type are contained in thechannel. The ejector-bar has also been 'found heretofore to rebound uponrem-hing its.norrnal retracted position in such a manner as to throw-itagain in gear, thus causing the ejection ofa second *f we.

.ln the present invention l have overcome these'defects by animprovement in the pianner of securing the springs whereby the. ejector-bars are returned to their normal position. A close coil-spring 22has one end secured to a stud 17 on the iixed cross-bar 23, and theforward ond is secured to the upper end of a pin 2l, which is attachedto thc typeejccting har 10. lt is to be observed that the spring acts onthe pin, :forininga 'part of the ejector-bar at a point substantiallyabove the latter and above the guide for the front end sis IOO

of the bar. n other words, the spring nete on the brrr at e pointsubstantially out of line with the teeth :ind the guide at the iront oithe bar, so that it hns n constant tendency to throw the rear end oi thebnr downward. l t will he evident that the pull ol' the spring o n theupper end of the pin 21, will canse the ejector-bnr to drop more quicklythan heretolore and will prevent any tenijlenoy of the rear endrebounding into geur when it strikes the stop 1.8. "lhe use ol. thespring in this nninnir thus allows the type-eieeto'r har 1U to he lnmdevery inueh lighter 1n weight, marking the entire operation of' theineehzini'bin inueh easier end quieter. .lt is to he noted that theSpring Applied in the deserihed relirtion to the hnr serves; threepurposee: first, that of retrnrfting the hair endwise when it isdisengaged 'from the roll 15"z seeond, that of insuring thedisenfenigelnent of the har :rnd quiekening i:rl downward movement 'whenthe lip l2 puber ward oi' the enin H; third, that o" holding the lmrdown no that there will he no danger oi' its rebounding undnecidenta-lly rengaging the roll.
